Tiny baby vs. household objects: Which is bigger?

It all started when a mom took a photo of her newborn daughter using a dollar for scale.

When a mom of two named Jen G. gave birth to her third child last month, she wasn't sure what to expect. Her newborn daughter, Alexandra, was born early (37 weeks), but not quite premature, and she was much smaller than her other two children had been when she'd brought them home. Jen was amazed at how teeny-weeny Alex was, and started documenting her daughter's size on her Instagram account, herewegoajen, by showing Alex in comparison to common household items.

Throughout her pregnancy, Jen's doctors kept a close eye on her because she has a clotting disorder and a history of Intrauterine Fetal Demise (IUFD). Early on in the pregnancy, her doctors also discovered that she had a circumvallate placenta, essentially a disease in which the fetal membranes double back around the edge of the placenta, forming a doughnut shape around the baby.

By Jen's 35th week of pregnancy, her stress tests started to indicate that the circumvallate placenta might be causing issues with the baby. Her doctors decided to induce as soon as Jen hit 37 weeks, technically no longer premature, but still earlier than they had hoped.

Fortunately, Alexandra was born without a hitch. But she weighed a mere 5 pounds, 7 ounces and measured 18 3/4 inches long.

Jen decided to capture every moment of Alex's teeny-ness. She took this photo on their first night home from the hospital and couldn't get over how silly it looked, "Like someone had photoshopped a baby in the room and gotten the sizing all wrong," she told Babble.
